Abstract
In the present work, ultrasonic velocity (u), viscosity (η) and density (ρ) of ternary mixtures of 1-hexonal
and 1-octanol with dimethylformamide in toluene at 303.15 K have been measured over the entire
composition range. From the experimental data, acoustical parameters such as adiabatic compressibility (β), intermolecular
free length (L ), free volume (V ), acoustic impedance (Z), excess adiabatic compressibility , excess free length , excess free f f
E E (b ) (L )f
volume and excess acoustic impedance have been computed. The variation of these properties with composition are E E (V ) (Z ) f
discussed in terms of molecular interactions between unlike molecules of the mixtures.
